Checking out the tracking informations I can see Houssam has received the package. Everything seems to have went well in spite of Saudi Arabia has recalled its ambassador but I assume it has nothing to do with the GTS crankshaft.

Is the car back together yet?

shaikhzeep

Good afternoon to every body,

Yesterday i brought the car from Kuwait.Today i have the chance to drive the car for the first time after i bought this car two years ago.

I drove the car in ambient temperature about 44C.The engine cooling system was okay.The gear shifting was smooth.By the way i overhualed the automatic transmission because there was abnormal sound coming from transmission.The gear shifting very smooth.The engine sound very quaite.

Then i decided to drive the car on highway as today Friday and every body sleeping soooo empty street.I drove the car and i took it to 120KM with smooth ride and good parameters on calister.I really do not want to push it more than that because the engine is just overhauled.

I really thanks who support and provide the crank shaft and the pistons.

Now , what my friend mechanic did with the block in details i really do not know.I know they took it to very famous machine shop and repaired the engine block.

I remember someone asked me about the condition of the old pistons.Well i recieved them and i found some deep scores on each piston side shell.I think this is because of the thrust movement.

I agree with some guys in the engine block can be repaired and machined if it is between good machining hands.

Actually i was afraid of high cooling temperature but no worry as the AC was on and ambiant temp is about 44C in city traffic with no issues.

Is it early to judge on engine workmenship.Well i really do not know.But to me everything is working fine.

If any body can add something or comment by all means.

to Strosek Ultra, do not worry the ambassodor will come back.Sweeden still friends to us.

I attached some photos took today

Houssam good to hear your truly nice car rolls again. Yes, I know your ambassador is back in Stockholm making everybody happy. An ambient temperature of 44C (111F) is way too much for a viking like myself.

Well if you made it from Kuwait to Dhahran safely that is a good start- presumably about a 3 hour run plus border crossing time?

It would be interesting to know exactly what the engine shop did for you assuming they were repairing a thrust bearing failure motor. Are you sure the pistons were badly scored?

Best wishes

Thanks for your concerns.Regarding the pistons they really have deep scores on the side of the pistons service.

Thanks

did they "fix" that block and how did they do this?? thats a lot of damage... wouldnt it have been better just to find an old S4 block and use it?

mark kibort

Does the metal shavings go up to the heads.... I would think that dirty oil would have to be pumped to the filter frst before it ever gets to the heads, right? if you say is correct, then everything up top could be junk too, or need to be cleaned up with extra care.

as a side note, how did they repair the bores, unless they just did an alusil coating job. (just cleans up the bores) any "work" done on them would give too much of a tolerance for the pistons to ride in the larger diameters ( if they did some bore work)

Im also curious about the TBF..... doesnt all the force ride on that main bearing? what does the fact that the counter weights digging into the sides of the block girdle, have on the TB? does that matter and why would it need to be cleaned up?
Im just trying to understand the TBF.... as it wears out, does it go away and then the crank counterweights touch the block sides??
as greg has said, usually this kind of failure has small cracking in the block water jacket paths, and that could be a problem down the road. might even be a problem now, if you are overheating first time out.... these things should run cool on the byway at ANY temperature outside. I run races at 110 degrees F, with the temp gauge right on the middle, with only one fan spinning.
overheating is a serous issue.... what was the temp guage showing? 3/4 high?

what rods did he end up using.... the R1s that came out, or the newer version R2?

Mark why not start a new thread on thrust bearing failure.... then it does not clutter up this thread. His engine is in the car and running there is little or nothing to be gained by questioning it further.
No need to cast doubt about what is already done especially if as you state you do not fully understand Thrust Bearing Failure.

mark kibort

that's rude Jim..... its a discussion. im curious bout the re-build.
im also curious about the high level issues with TBF. I think its an appropriate forum for questions.
your comment is clutter jim... plain and simple.. now we have two comment posts with no purpose......

edit: especially, since the "experts" here said the block was junk at the start. Ive heard that before and had great success either due to luck or knowledge that the appropriate areas of the part in question, was not as bad as the pictures had shown.

Happy for you that your efforts managed to save your beautiful car

Wishing you many miles/KM's of save GTS driving time.

Enjoy the experience and may it bring you many smiles for years to come...

Mark,

The item about cleaning the system comes from the workshop manual that I wanted to bring to Houssam's attention- like you it surprised me a little the first time I saw this. I suspect the logic is that when a motor suffers catastrophic failure of this kind the detrius goes beyond the capability of the oil filter to resolve it - not too surprising given this is not a normal design scenario. I remain somewhat puzzled as to why the lifters should be considered "throwaway items"- probably because they are dead ended and thus difficult to flush out with any certainty.

Houssam was given very sound advice about the complexities of this issue and he has made decisions about what action to take. I sure hope he gets a good result that will keep him going for a long time to come in what looks to be a very nice example.

I trust he has taken appropriate action to ensure the problem does not reoccur!

Rgds
